The lady and the dungeon

He had dreamed of this night for many long months now; and had planned every minute detail. The time had come for him to put the Master plan into operation. The relationship with his lady friend, was on the whole very satisfying, but it was a bit tame compared to the wild sexual adventures he often conjured up in his demented mind. She was a good girl with a fantastic tight body that any man would be proud to caress, fondle and devour, but he was sure there was another hidden side to her nature. He had no real basis for his suspicions, but over the time that they had been together he had observed her closely, and noticed that the way she moved her body was purely sexual.
